Warren DeWitt was a 76-year-old unmarried gentleman who lived alone. 90-year-old Arden Peters was struggling to care for his Alzheimers-stricken wife. When the two men met over breakfast at a local Wal-Mart one morning, they struck up a friendship that would ultimately ease the burden of old age for both of them.

Friends for Life is an excerpt of "Aging in America: The Years Ahead," a groundbreaking, many-faceted film by multimedia innovators Ed Kashi and Julie Winokur. In it, they explore the various challenges faced by the fastest-growing segment of the American population. As Arden says, "When you get this old you don't look forward — you just live day to day."
